Subject: [PATCH 7/9] Input: ab8500-ponkey: Create AB8500 domain IRQ mapping

Before we can use any domain allocated IRQ, we need to first create a
map between the Hardware IRQ (hwirq) and the Linux Virtual IRQ (virq).
We do this with a helper function provided by the AB8500 IRQ domain
controller called ab8500_irq_get_virq(). We need to do this for both
IRQs which the Power-On-Key driver uses; one for button press, the other
for button depress.
